BICYCLE-SADDLE.

SPECIFICATION forming part of Letters Patent No. 546,350, dated September 17, 1895.

Application filedJ'une 24, 1895. Serial No. 553,821L. (No model.)

To all? whom it may concern:

Be it known that I, BENJAMIN S. SEAMAN, a citizen of the United States, and a resident of Canton, county of Stark, State of Ohio, have invented a new and useful Improvement in Bicycle-Saddles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to improvements in bicycle-saddle frames and supports; and it consists of certain features of construction and combination of parts, as will be hereinafter described and claimed.

Figure 1 of the drawings is a perspective illustrating my invention. Fig. 2 is a similar View of a nut by which the saddle-frame is secured to the post. Fig. 3 is a similar view of the upper end of the post. Fig. 4 is a cross-section of the body portion of the saddle-frame in line a: as, Fig. 1. Fig. 5 is a perspective of the binding-link. Fig. 6 is a longitudinal section through the adjusting device. Fig. 7 is a perspective of pommel-support. 7

A denotes a tubular frame or body having secured to its rear end portion a rigid truss cantleframe B, formed substantially as shown, and consisting of the following members or portions: the circular rear portion a, to which the rear portion of the seat-leather may be secured, the end portions of which are bent back on itself and secured to the rear portion a, as shown at b, and forward and into the tube A, and the braces c, secured to the first mentioned member, as shown at d. The other ends of said braces are passed into the tube, as shown,in which position the parts are secured, thus forming a light, strong, and absolutely rigid cantle-frame.

The bottom portion of the tube A is made fiat from y to y, thus forming that portion; of the tube semicircular in cross-section, "as shown in Fig. 4, thus forming a flat surface to rest on the top of the post B, which is formed of a section of tubing, as shown, having welded into its top end aplug e, in which is formed a slot or recess f to receive the binder G. (Shown in Fig. 5.) About the top end of the post B is provided an annular thread 77., adapted to the thread 7c in the tightening-nut D. The binder O is provided at its lower end portion with projections m to engage the nut D, and at its upper portion with an aperture 71 to receive the tube A.

In operation the binder O is placed in slot f, the nut D turned on a distance, the tube A passed through the binder, and the not turned down to secure the saddle-frame to the top of the post. At the front end of the tube A is provided a threaded nut F, in which is turned a tightening-screw G, having a spindle portion '5, that rests in the aperturej in the pommelsupportI-I. In the head of the screw G are provided apertures, in which a pin may be placed to turn the screw into or out of the tube A to tighten or slacken the seat-leather on the frame. I have purposely omitted the seat-leather in order to more fully show the frame. The seat-leather may be of the usual form, secured to the cantle-frame and pom incl-support in the usual way.

To adjust the saddle on thepost, the nut D is turned back a distance to slacken the binder, when the tubular part of the frame may be moved through the binder to adesired position and secured by the nut D.

Having thus fully described the nature and object of my invention, what I claim is 1. The combination in a bicycle saddle of a central tubular support, having at its rear end an open rigid cantle frame B, curved in its middle part to conform to the leather seat, the ends bent forward and inward and back, and secured to the back, the free ends bent forward to the rear part of the tube, and the braces c, secured to the frame B, and the tube A, and at the front end of the tubular support, a means for adjusting said frame or support to the saddle leather, substantially as described and for the purpose set forth.

2. The combination with a bicycle saddle frame, of the post B, having at its top end an substantiallyas described and for the purpose annular screw thread, a slotf, the binder 0, set f0rth.. V I and a nut D, substantially as described and In testimony whereof I have hereunto set for the purpose set forth. my hand this 17th day of June, A. D. 1895.
